71b58d6c5e this testcase is failing because pic16 doesn't define a reg/reg 
xor pattern.  I have no plans to fix this XFAIL.

b5031ad4c0 Removed the extra S from the multiclass def T2I_adde_sube_s_irs as well as from 
the opc string passed in, since it's a given from the class inheritance of T2sI.
The fixed the extra 's' in adcss & sbcss when disassembly printing.

c4f7ec85ec When expanding an expression such as (A + B + C + D), sort the operands 
by loop depth and emit loop-invariant subexpressions outside of loops.
This speeds up MultiSource/Applications/viterbi and others.

82dd3d38d9 Fix the xfail I added a couple of patches back. The issue 
was that we weren't properly handling the case when interior
nodes of a matched pattern become dead after updating chain
and flag uses.  Now we handle this explicitly in 
UpdateChainsAndFlags.

c6d7ad3c7d Rewrite chain handling validation and input TokenFactor handling 
stuff now that we don't care about emulating the old broken 
behavior of the old isel.  This eliminates the 
'CheckChainCompatible' check (along with IsChainCompatible) which
did an incorrect and inefficient scan *up* the chain nodes which
happened as the pattern was being formed and does the validation
at the end in HandleMergeInputChains when it forms a structural 
pattern.  This scans "down" the graph, which means that it is
quickly bounded by nodes already selected.  This also handles
token factors that get "trapped" in the dag.

Removing the CheckChainCompatible nodes also shrinks the 
generated tables by about 6K for X86 (down to 83K).

There are two pieces remaining before I can nuke PreprocessRMW:
1. I xfailed a test because we're now producing worse code in a 
   case that has nothing to do with the change: it turns out that
   our use of MorphNodeTo will leave dead nodes in the graph
   which (depending on how the graph is walked) end up causing
   bogus uses of chains and blocking matches.  This is really 
   bad for other reasons, so I'll fix this in a follow-up patch.

2. CheckFoldableChainNode needs to be improved to handle the TF.
